A bat blundered into the nest of a weasel, who ran up to catch and eat him. The bat begged for his life, but the weasel would not listen. "You are a mouse," He said, "And I am a sworn enemy of mice. every mouse I catch, I am going to eat!""But I am not a mouse!" Cried the bat. "Look at my wings. can mice fly? why, I am only a bird! please let me go!"The weasel had to admit that the bat was not a mouse, so he let him go. But a few days later, the foolish bat went blindly into the nest of another weasel. This weasel happened to be a bitter enemy of birds, and he soon had the bat under his claws, ready to eat him. "You are a bird," He said, "And I am going to eat you!""What," Cried the bat, "I, a bird! why, all birds have feathers! I am nothing but a mouse. 'down with all cats,' is my motto!"And so the bat escaped with his life a second time.
